Glow sticks are always awesome .From Concert to campfire,child to old people all love the Glow Stick.Glow Stick s a self-contained, short-term light-source.It was invented backs in the 90's around 1965.Basically Glow Stick consists of a translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence, so it does not require an external energy source.The light cannot be turned off, and can be used only once.

===========================================================

I Always wanted to make My Own Glow Stick . So I made a led One to have the fun with it also the glow stick Could gave me opportunity to click some cool light trails photographs

But this one will use led for giving the effect,so you can turn it on and off anytime you want.

============================================================

Advantages of LED Glow Stick

  1. Since its electronic, potential danger ,due to the spilling of chemicals in chemical glow sticks, is absent
  2. It is cheap and easy to make at home
  3. Can be reused only changing battery will be required.
  4. Can be turned on and off easily

So lets make one :)

Step 1: List of Material

Components

  1. Battery 3v button cell (CR2032)(Electronic Store)
  2. 5 mm LEDs (Electronics Store)
  3. 5 mm transparent pipe (Hardware Store)

Tools

  1. Glue Gun
  2. Cellotape

Step 2: Putting the First LED Inside the Tube

  • Apply a little glue at the end of the transparent tube.
  • ( Note the length of the tube should not much . I used around 15 cm length tube.)
  • Push the LED in to the tube .make sure its Air tight .
  • If you don't have glue gun,simply push the led inside tightly.
  • Use the Cello tape to block the led.Tightly Wrap It to make it water Tight

Step 3: Fill the Tube With Water

  • After u have sealed one of the end with glue and led ,fill the tube with water till the other end.
  • keep a little space to glue the other end the second led.
  • You can use a syringe to fill the water.
  • After filling the tube with water add little cornstarch to diffuse the water.
  • apply glue to the end and push the second led tightly.It should look like the image .

Step 4: Check the Seals

  • Check the seals to ensure no water comes outside.
  • If It comes out then don't worry apply a little more glue and tap it.(if you didn't apply glue and poured water .no need to check seals.:P).
  • I put black tape around the tube to hide the glue part.

Its ready now time to connect the battery.

Step 5: Its Time for the Battery to Talk

Connect the leads to the button cell properly and enjoy.

Step 6: Some Fun With It

Here are some light trail photos i clicked with the Glow Stick.

<p>You can add a bit of cornstarch to the water to make it &quot;just a little cloudy&quot; -- then you'll have a lot more light coming out of the tube.</p>
You can even fill glycerine
<p>Adding a tiny bit of bleach could work. It works for those people doing the water bottle ceiling light in other countries. Milk in the water could be another alternative but its not something I would put a lot of faith into. </p>
<p>Thank you i will definitely try it </p>
<p>I took a white led and connected it the same way as you did to a USED battery that was too discharged to keep the clock of a computer going. It gave me usefull light for three weeks so the battery if fresh should last quite some time</p>
<p>it would be interesting if the estimated price for the project was listed - especially as people are doing the all over the place. </p><p>What has this glow stick run you to make?</p>
price of one is less than a $
<p>Love them!! That reminds me on my old-school bike, I put 4 of them on my wheel spokes. It really grabs people's attention when you ride that bike all night long through the street.</p>
can you share a pic of your bike
<p>Seriously wow!</p>
thanks
<p>A few years back I picked up a gallon or so of the reflective glass beads the road crews spray into the paint when Striping the lanes.</p><p>Filling the tune 1/4 - 1/2 before adding water and cornstarch may make a nice effect as well.</p><p>Since the cost is minimal, I think mineral oil might make a good medium as well.</p>
<p>Where can one get some of that reflective beads stuff? I've been looking for it to cover my mailbox so I can find my house at night with my headlights!</p>
I stopped a striping crew when they were in front of my house.<br><br>You might look up the city or county Dept of Roads and Bridges, or your local State Dept or Transportation and ask them.<br><br>They work best when sprayed into a fairly thick coat of paint<br><br>
<p>if you use the ultraviolet LED's and ill the tube with Tonic water, it will glow better!</p>
<p>Yes, tonic water really DOES glow with UV light shining on it! To think, folks drink the stuff, too! Bitter as far as I'm concerned. But ultra-cool for glowing. </p>
<p>Oh I love the stuff! it is a bioluminescent so it isn't poison. Tonic (Quinine) was used to help keep British soldiers from catching Malaria. The best way to keep them taking it was to turn it into a alcoholic beverage. but if you look at a few bars where they have glowing bottles they are filled with this stuff and a black light is used. <br><br>My wife and I have been working on a face piece for her for halloween, using this method with LED's to give a more cyborg / zombie rotting effect. (Skin falling off exposing pipes and wires. our hardest part right now is keeping it light enough with the skin to keep it from falling off. stage makeup/glue is good stuff but not for 4 hours or more. </p><p>Another idea for adding stuff into the tube is hair gel with a mix of glow powder from Unitednuclear.com. then you could use a white or the UV to charge the powder suspended in the gel. this is my next try. one issue i have already found is I need some sort of Cake icing thing to squeeze the gel/powder into the tube. I have already tested on some small glass bottles. </p>
Or use antifreeze.
<p>hmm better tnks fr suggestions.:) :)</p>
<p>I like this 'ible - simple, and yet dramatic.</p>
<p>cool exept i could get 15 glowsticks for a euro in the pound shop</p>
<p>They don't last very long at all. Trust me, if you have a sleepover party with six 4 year olds and two glow sticks go out early? </p><p>Life.</p><p>Over.</p>
<p>Hahaha - SO true! I like that it can be turned on / off, and lasts much longer if needed, and with the change of battery, can continue!</p><p>Good 'ible!</p>
<p>you could, but where's the fun in that?</p>
<p>Is that consider complete? How you can swing it with the battery just tape it? </p>
<p>Sorry if this a duplicate, I don't think it went through the first time. </p>
wonderful ,try wrapping a black tape at the end .
<p>Has anyone tried putting aluminum foil or other reflective material around the ends of the tube where the LED's are placed? I would think this might help to reflect more of the light upward into the tube.</p>
<p>I wonder how it would look with salt in the tube in place of the water?</p>
<p>Do try it Even i am curious to see it</p>
It works! I don't think it's any brighter than just water, but at least it can't leak.
<p>Neat Idea, could you please give more details on how the battery is connected ?</p><p>This would be perfect to put inside &quot;craft stick&quot; lamps/lanterns ! Thank you </p>
<p>I found these at the dollar store. Finger lights for kids. All you need plus a switch! Gonna try this with salt snd wii post.</p>
<p>Very cool idea, we will def try this...</p>
<p>Do share a Pic after you make it</p>
That's pretty cool. One minor thing. In your instructions, you mentioned it was first created in the 90s, in 1965. Was the led version made in the 90s and the original in '65?
<p>1965 was the original one</p>
<p>Really fun simple project! Nice job!</p>
<p>Thank You</p>
<p>This looks so simple that even I will try it. Thank you Prajjwal, I am an old lady and I would never have tried anything like this had I not seen your instructable. Thanks again from Aussie lady. </p>
<p>Thank You Mam <br>Please Do share a Pic after u make it.</p>
Someone suggested using oil instead of water. <br>I'm not 100% sure, but I think that may compromise m the &quot;stick&quot; tube. I am not sure how hot glue would hold up to the oil, but if it got on the tape, it would lose adhesive properties.
<p>what was the cost of leds &amp; power cells and tubing</p>
<p>Thats SOOO cool</p>
<p>Woaa dude really cool !!!<br></p>
Nice job! I like how the two led colors blend in the glow stick.
<p>I missed where the two CR2032 batteries go!</p>
<p>It's simple</p>
It's cool and all. not ur idea. kipkay did it first way back
<p>I guess U have not seen this properly before u posted this comment kipkay used glue stick as the medium i used a tube filled with water that is totally different from kipkay's one Beside this is 100% my idea inspired from kipkay Glue Stick version.<br><br></p>
